The materials usually processed by Dongguan automatic lathe are free cutting steel and copper. The free cutting steel has high sulfur s and phosphorus P. sulfur and manganese exist in the form of manganese sulfide in the steel, and manganese sulfide plays a lubricating role in the steel, making the steel easier to cut, so as to improve the production progress of the lathe.

Automatic lathe processing features:

1. The cutting process is relatively stable; In addition to the intermittent surface, generally, the lathe processing process is continuous. Unlike milling and planing, the cutter teeth cut in and out for many times in one cutting process, resulting in impact;

2. Suitable for finishing of non-ferrous metal parts; For some non-ferrous metal parts, due to the low hardness and good plasticity of the material itself, it is difficult to obtain a smooth surface by other processing methods;

3. Simple cutting tool; Turning tool is the simplest tool in the automatic lathe processing series. It is very convenient for manufacturing, grinding and installation, which makes it easy to select a reasonable angle according to the specific processing requirements.
